Its site EUI of 67.3 kBtu/ft² is about 14% below the average of 78.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 102,807 sq ft, it is about 15% below the average floor area of 121,167 sq ft for those buildings. It was built in 1989, 24 years later than the group's average year built (1965). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has 1035 Cambridge Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 1035 Cambridge Street, covering report years 2015–2024. Its ENERGY STAR score went from 81 in 2015 to 68 in 2024 (-13 points); its best year on file was 2016, at 83. Site EUI moved from 51.1 kBtu/ft² (2015) to 67.3 kBtu/ft² (2024), an 32% increase. Reported emissions went from 370 tCO₂e to 455 tCO₂e over the same span (up 23%).
What does an ENERGY STAR score of 68 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 68 means the building performs better than about 68% of its national peers. BuildingCensus bands the score into report-card grades; 68 falls in band C — below median (55–69). It sits 7 points below 75, the threshold for ENERGY STAR certification. In Cambridge, 50% of scored buildings are at 75 or above.
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. 1035 Cambridge Street's 67.3 kBtu/ft² across 102,807 sq ft works out to about 6.9 billion Btu (2,028 MWh-equivalent) in 2024. Its source EUI of 149.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,353,918 kWh of electricity, 22,944 therms of natural gas and 64,146 thousand gallons of water for the year.
Which law requires 1035 Cambridge Street to report its energy use?
